The spire is about the length of the aperture and has straight sides, variable color pattern and shape. Aperture is stained pink. Found throughout Pacific including Hawaii.. Biconic in shape with the spire shorter than the aperture. Spire sides are straight to slightly concave. Spire whorls are convex with 4 convex, spiral cords on most whorls. Closely spaced axial riblets node the cords slightly. Cords continue on the body whorl to the anterior tip. The mature lip extends spirally with a callus covering. There are about 12 spirally elongate denticles on the wide edge of this callus with cen¬tral denticles high and decreasing in height to the anterior and posterior. The denticles correlate with the external spiral sculpture. The posterior canal is long and fairly narrow, crossing the wide lip. The parietal wall is convex from the suture to the columella that is convex to near the anterior tip and bears about 8 glossy denticles. There is a columellar callus outside the denticles that increases in width at the posterior of the columella to its anterior end.
The color pattern has spiral lines that give the appearance of spiral cords. There are wide dashes that cross the "cords". It is a wide shell with the body whorl convex from the suture to the fasciole. The spire length is about half that of the aperture. Spire sides are concave. The outer lip is thick with 5 denticles, the center two larger than the others. The columella has 5 rounded denticles closely spaced.

This species is also widespread and occurs from South Africa through the Indian Ocean and Indonesia, north to the Philippines and southern Japan, and east to Hawaii and French Polynesia. The shell is globose, 10 to 15 mm long at maturity, with 5 to 6 teleoconch whorls. Shell colour and pattern are quite variable, generally consisting of some pattern of light brown on white, but the aperture edge is always pink. There are two large columellar folds. The protoconch varies in colour but is frequently pink, with 3.5 to 3.75 whorls and axial threads. Early spire whorls are nodulose at the periphery, as in other Euplica species.

The outline is almost globular. The spire is small, but pointed. The inner lip margin bears 2 rows of minute teeth on its posterior part, while the outer lip is simply toothed. The smooth, light brown surface is marked by a spiral zone of white spots. This is beautifully reddish purple inside the aperture. Distribution: south of central Honshu, below the tide line.
